The period t 1 to t 2 during which the additional current IP flows is set to, for example, a period of about 1/4 of the initial period t 1 to t 4 during which the programmed current I m flows. The additional current I p is allowed to flow. The period t 1 to t 2 is set at the beginning of the programming current I m, but the additional current I p is intended to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) to the paper size of the luminous hue. -18

I22TW A7 B7 V. Explanation of the invention (4 The effect of the suppression is minimized. Also, the value of the additional current IP is set to, for example, about the middle of the maximum current and the minimum current of the programming current I m. Correctly speaking The output current l0ut shown in Fig. 7 (a) shows the current driving capability of a single line driver 4 10, and the real current 値 I s on the data line X m changes as shown by the solid line shown in Fig. 7 (b) That is, at time t1, although the large current flowing in the transition will gradually decrease, it will gradually approach the current 値 (I m + IP). And at time t2, the additional current circuit 4 3 0 is turned off. The real current I s decreases even more at this time. However, after the time t 2, the current 値 itself is smaller, which causes the speed of the charge or discharge data line capacity C d (Figure 3) to decrease. As a result, the change ratio of the current 比 to t The period from 1 to t 2 is slow. However, at time t 3, the real current I s is reduced to the programming current 値 I m ′ and the programming current 値 I m is maintained during the period t 3 to t 4. Therefore, during programming During the period T pr, the pixel circuit 2 1 0 is programmed with the correct programming current 値 I m. Benefits of this additional current IP It is also possible to consider the operation of “changing the programming current 値 I m from the first current 时 at the last programming time to the second current 时 at the current programming time. Most of the periods (periods t 1 to t 2 and periods t 2 to t 3 in FIG. 7) are performed. ”The change from the first current 値 to the second current 値 is performed by the program at the time of the program. The third current 値 (I m + I p), which is the sum of the current I m and the additional current I p, is performed. The point-locked line shown in FIG. 7 (b) shows the current of a single line driver 4 1 0 without the additional current I p When the driving capacity is certain (Figure 7 (This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm)) -19-(Please read the precautions on the back before filling this page), and order the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employee Consumption Cooperative 1221598 A7 _B7_ V. Description of Invention () 7 (Please read the notes on the back before filling this page) c)) The real current 値 changes. At this time, due to the current t 1 ~ t 2 Compared with the case where the additional current IP is used, the current change is slower. Therefore, at the end of programming t 4, there may be cases where the real current 値 I s 尙 does not reach the programming current 値 I m. In this case, it is impossible to program the pixel circuit 2 10 to the correct color tone. Or, in order to perform the correct programming, a problem occurs in which the programming period T pr needs to be extended. Therefore, when the additional current IP is used, the correct programming can be implemented in the programming period T pr. Figure 8 shows the programming. The display of the change in the charge amount Q d of the data line X m of T pr during the program is illustrated. Fig. 8 depicts the operation of Fig. 7 from the viewpoint of the amount of charge. In addition, the time components t 1 and t 4 in FIG. 7 correspond to the time components in which the level of the first gate signal V 1 changes, as shown in FIG. 8. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Before the programming of the pixel circuit group in line η, the capacity of the data line Xm 値 Q c 〇 depends on the programming of the pixel circuit group in line (η-1). The programming current 値 I m of the data line X m. FIG. 9 shows the relationship between the light-emitting color G of the organic EL element, the current 値 I m (that is, the programmed current 资料) of the data line X m, and the charge amount Q d of the data line X m. In the circuit configuration of the first embodiment, the higher the hue G (that is, the higher the brightness), the larger the current I m and the lower the charge amount Q d (that is, the voltage V d) of the data line Xm. The charge amount Q d is a charge amount equivalent to a voltage close to the power supply voltage V d d in the lowest tone G nr i η, and a charge amount equivalent to a voltage close to the ground voltage in the highest tone Gm a X. Moreover, the example in Fig. 8 (c) assumes that the programming current 値 I m of the previous programming (that is, the (n-1)) programming is large, which is also the paper size of this programming format applicable to China. National Standard (CNS) A4 specification (210X297 mm) i-20-1221598 A7 B7 V. Description of the invention (case where the amount of charge Q d 0 before the beginning is small. (Please read the precautions on the back before filling this page) When the programming is started at time t 1 in FIG. 8, the data line X m is charged or discharged by the output current lout (= (im + Ip)) of the single line driver 410, and the amount of charge Q cl increases at a faster speed. And at time t2, when the additional current IP becomes non-existent, the change in the charge quantity Qd also becomes slow. However, at time t3 within the programming period Tpr, the corresponding programming current 値 I has been reached The charge amount Q dm of m. As can be seen from the above description, the additional current circuit 430 functions as a charge / discharge acceleration unit for charge or discharge acceleration of the data line Xm. In addition, in this specification, the so-called "acceleration of charge or discharge" Compared with only the better current 値 (in this embodiment, the programming current 値 I m) Charging or discharging can end the charging or discharging in a shorter time to promote the charging or discharging operation. In addition, the additional current circuit 430 can also be considered as an acceleration means that accelerates the current change with the change of the data signal, or Update the charge amount of the data line X m to the update method used by the fixed line. The employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economics prints a point as shown in Figure 8 (c). When there is no additional current I p, the charge / The discharge rate is kept low. In this example, at the end of the programming period T pr, the charge amount Q dm corresponding to the desired programming current 値 I m has not been reached. Therefore, it is impossible to supply the pixel circuit 2 10 Correctly program the current I m to program the possibility of correct hue. If so, in this embodiment, by using the additional current IP to accelerate the charging or discharging of the data line, the pixel circuit 2 10 can be correctly programmed. In addition, the programming time can be shortened, and the drive control of the organic EL element 2 2 0 can be made faster.

V. Description of the invention (A 'also uses the additional current I p to accelerate the charging or discharging of the data lines. Usually, all the data lines X m included in the pixel circuit matrix are performed simultaneously. However, only the majority Some of the data lines can also be used to selectively charge or discharge the accelerated data line using the additional current I p. For example, the m-th data line xm's charge Qd0 (Figure 8) is very close to the start of programming When the charge quantity Q dm corresponding to the programmed current im is not required, the additional current I p may not be used. Specifically, the controller 100 compares the programmed current of line (η-1) with each data line and The programming currents 行 in the η line are compared with each other. If the difference is within a predetermined threshold 则, it can be judged that the additional current I P is not used during the programming in the η line. Moreover, the difference in the programming currents 促使 corresponding to the difference causes the additional current I ρ can also be changed. In other words, a means corresponding to the difference between the previous 値 and 値 of the programmed current 値 I m to determine the additional current I ρ current 与 is provided, and the determined additional current 値 IP is supplied to the data line. X m According to this configuration, the additional current 値 I ρ can be used more effectively to promote high-speed driving. Or, only when the current 编 I m is smaller than the predetermined threshold 编 is programmed. Use the additional current IP to program If the current 値 I m is larger than the predetermined threshold 予以, it may be judged that the additional current IP is not used. The reason is that when the programming current 値 I m is large, the charging and discharging of the data line X m is performed very quickly, resulting in It is possible to achieve a very high-speed desired programming current 値 I m without using the additional current IP. Instead, only the current programming 値 (second current 比) is larger than the previous programming current 値 (first current 値). It is small, and the current paper size of this program applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives -22- 1221598 A7 B7 V. Description of the invention () 0 (Please read the precautions on the back before filling this page) 和 The sum of I m and the additional current 値 IP (the third current 比) is larger than the current programmed last time 値 is hour It is also possible to use the additional current I p. The three currents 亦可 can also be set to have other relationships. For example, the third current 値 is set to the current between the first current 値 and the second current 値Also, the current / time change rate of the first current 第一 to the third current 设 is set to be larger than the time change rate of the current 第三 to the third current 値 to the second current. The absolute value of the difference between a current 値 and the third current 値 may be set to be larger than the absolute 値 of the difference between the third current 値 and the second current 。. Whether to use the judgment of the additional current IP and compare it with each data line However, regardless of the programming current during the previous programming, if the additional current IP is often used, the control of the entire display device becomes simpler. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs As above, in this embodiment, by adding the additional current I P to the programming current I m at the beginning of the programming period, the correct programming can be performed in a short time. Or, the programming time can be shortened and the drive control of the organic EL element 2 2 0 can be made faster. In particular, as the size and resolution of the display panel are required to increase the speed of driving control, the above-mentioned effects are significant in large-scale display panels or high-resolution display panels. B. Second embodiment (second additional current): FIG. 10 is a block diagram showing a schematic configuration of a display device according to a second embodiment of the present invention. This display device is different from the first embodiment in that a data line driver 4 0 a is provided on the power supply potential V d d side. In addition, as explained below, the internal structure of the single line driver 4 1 〇a and the pixel circuit are in accordance with the Chinese National Standard (CNS) A4 specification (210X297 mm) -23- 1221598 A7 B7 V. Description of the invention (4 2 1 The internal structure of 〇a is also different from the first embodiment. (Please read the precautions on the back before filling this page.) Figure 1 is a circuit display diagram of the pixel circuit 2 1 〇a. This pixel circuit 2 1 0 a has an organic EL element 2 2 0, four transistors 241 to 244, and a holding capacitor 230. The four transistors 24 1 to 24 are p-channel FETs. The data lines X m are sequentially connected in series. The first transistor 2 4 1 ′ is connected to the holding capacitor 230 and the second transistor 242. The drain of the second transistor 2 4 ′ is connected to the organic EL element 2 2 0. The first and second transistors are connected. The gates of the crystals 241 and 242 are commonly connected to the first auxiliary gate line V 1. Between the power supply potential V dd and the ground potential, a third transistor 243, a fourth transistor 244, and an organic EL are connected in series. Element 220. The drain of the third transistor 243 and the source of the fourth transistor 244 are also connected to The drain of the first transistor. The gate of the fourth transistor 2 4 4 is connected to the source of the second transistor 2 4 2. The holding capacitor 2 3 0 is connected to the source of the fourth transistor 2 4 4 Between the pole and the gate. The first and second transistors 241, 242 are switching transistors used to store the desired charge when printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and the Intellectual Property Bureau. The third transistor 2 4 3 is a switching transistor that is kept on during the light emitting period of the organic EL element 2 2 0. The fourth transistor 2 4 4 is a driving transistor required to control the current 値 flowing to the organic EL element 2 2 0. The current 値 of the fourth transistor 2 4 4 is controlled by the amount of charge held by the holding capacitor 2 30. Fig. 12 shows the pixel circuit 2 1 0 a of the second embodiment. Generally, the paper size applies the Chinese national standard (CNS). ) A4 specification (210X297 mm) -24- 1221598 A7 B7 V. Timing diagram of the invention description (i (Please read the precautions on the back before filling in this page). This action is from the first implementation shown in Figure 5. For example, the logic of the reverse gate signal VI, V2 is reversed. For example, as can be understood from the structure of FIG. 11, during the programming period T pr, a programming current I m flows into the organic EL element 220 through the first and fourth transistors 241, 244. Therefore, although the second embodiment is During the programming period T pr, the organic EL element 220 will also emit light. If so, during the programming period T pr, the organic EL element 220 may emit light or may not emit light as in the first embodiment. Fig. 13 is a circuit diagram showing a single line driver 410a of the second embodiment. The single line driver 4 1 0 a is connected to the power supply potential V d d of the data line X m. Therefore, the point that the driving transistor 4 2 of the data signal generating circuit 4 2 0 a and the driving transistor 4 4 of the additional current circuit 4 3 0 are both constituted by a P-channel FET is different from the first embodiment shown in FIG. 6. . The other structures are the same as those of the first embodiment. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 14 shows the light-emitting color G of the organic EL element 2 2 0 of the second embodiment, the current 値 I ^ of the data line X m, and the charge amount Q d of the data line. Relationship. In the second embodiment, contrary to the first embodiment, a single line driver 4 10a is set at the power supply potential V dd side of the data line X m to cause the color tone G and the charge amount qd of the data line X m (that is, the voltage V d) The relationship is reversed from the first embodiment. That is, the higher the hue G (that is, the higher the brightness) ', the more the charge amount Q d (that is, the voltage V d) of the data line increases. The charge amount Q d is equivalent to a charge amount close to the ground voltage in the lowest tone Gm i n, and is equivalent to a charge amount close to the power supply potential V d d in the highest tone Gm a X. This paper size applies Chinese National Standard (CNS) A4 specification (21〇X: 297 mm) " -25- 1221598 A7 B7 V. Description of invention ((Please read the precautions on the back before filling this page) Figure 1 5 The change of the charge amount Q d of the data line X m of TP r during the programming of the second embodiment is shown for display. This change is substantially the same as the change of the first embodiment shown in FIG. 8. However, in FIG. 15 (c) The amount of charge Q d 0 before the start of the programming is small, but contrary to the first embodiment, the programming current 値 I m when programming the previous line (ie, line (η-1)) is small The display device of the second embodiment also has the same effect as the first embodiment. That is, by adding the additional current I p to the programming current I m at the initial stage of the programming period T pr, The correct programming can be performed in time. Or, the programming time can be shortened and the drive control of the organic EL element 220 can be increased. C. The third embodiment (the third additional current): The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed Figure 16 shows a single line driver 4 1 0 b of the third embodiment The circuit diagram of the data signal generating circuit 4 2 0 in this single line driver 4 1 0 b is the same as the first embodiment shown in FIG. 6, but the structure of the additional current circuit 4 3 0 b is different from that of the first embodiment. That is, the additional current circuit 4 3 0 b has two sets of switching transistors 4 3 and driving transistors 4 4 connected in series, and these are in parallel with each other. The gain coefficient of the two driving transistors 4 4 is set without c ratio For example, 1: 2. The additional current control signal D p is also supplied as a 2-bit signal. When using the additional current circuit 4 3 0 b, the additional current 値 丨 p can be arbitrarily set to the additional current control signal. D p can obtain any one of the four levels corresponding to four 値 0 ~ 3. This paper size is based on 1 towel 11 national standard (milk) 纟 4 specifications (21 () / 297 mm) " ~ ' -26- 1221598 A7 B7 V. Description of the invention (4 Fig. 17 is a display diagram for explaining the operation of T pr during the programming period when the additional current circuit 4 3 0 b of the third embodiment is used. Here, the additional current 値 IP system Change from higher first level IP 2 to lower second level IP 1. As a result, compared with the first embodiment In the second embodiment, the data line can be charged or discharged more quickly. It can also be understood from this example that when the additional current is used, the additional current is changed by more than two stages, and the output current I out of the data line X m is divided into three stages. The above changes are also possible. In addition, when the additional current circuit 4 3 0 b of FIG. 16 is used, as in the first embodiment, the level of the additional current 値 IP may correspond to the programming current 値 and The programming current of this trip is determined. In this way, a suitable additional current 利用 corresponding to the programmed current 对应 can be selectively used. In addition, the additional current circuit 4 3 0 b using so many additional currents I P can also be applied to the second embodiment. D · Modifications of using additional current: The use of additional current can be modified in the following ways. D 1: The additional current circuit is not necessarily installed in a single line driver 4 1 0, as long as it is connected to the data line X m, it can also be installed in other positions. In addition, instead of installing an additional current circuit for each data line X m, an additional current circuit may be installed for most data lines. D 2: Also, no additional current circuit is provided, and the signal circuit for borrowing data is used.

Order the Ministry of Economy Printed by the Intellectual Property Bureau's Consumer Cooperatives -27- 1221598 A7 B7 V. Description of the invention (4 4 2 〇 During the initial programming period, a current greater than the programming current 値 I m 値 is generated, and after a predetermined time, it is switched to programming The current 値 I m can also be read (please read the precautions on the back before filling in this page) 〇 As you can understand from the above embodiments or modifications, if you want to use the additional current _ 'In the initial programming time, it will be greater than the programming current 値 I m It is sufficient to circulate a large amount of current through the data line. This can promote the charging or discharging of the data line and enable accurate programming and high-speed driving. E • Fourth embodiment (pre-charging) Figure 18 is a block display diagram of the display device according to the fourth embodiment of the present invention. This display device is provided with pre-charging on each data line Xm (m = 1 ~ M) of the display device of the first embodiment shown in FIG. 3 Circuit 6 0 0 is the same as that shown in Fig. 3. However, the capacitance C d of the data line is omitted due to the convenience of illustration. Moreover, a single line driver 4 1 0 can also be used without an additional current circuit. 4 3 0 (Figure 6): 0 The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed each data line X m, and a precharge circuit 6 0 was connected between the display matrix portion 2 0 and the data line driver 4 0 0. 0. The pre-charging circuit 600 is composed of a series-connected pre-charging power supply vp of a constant voltage power supply and a switching transistor 6 1 0. In this example, the switching transistor 6 1 0 is an n-channel FET, and its source The pole is connected to the data line X η. The gate self-controller 100 (Fig. 2) of each switching transistor 6 1 0 is commonly input with a precharge control signal Pre. The potential of the precharge power source V ρ is set to, for example, The driving power potential V dd of the pixel circuit 2 10 (Figure 4). However, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -28-1221598 A7 B7 5. Description of the invention (', can also be used Can arbitrarily adjust the power circuit of the pre-charged power supply VP. The circuit 6 0 0 is a circuit for charging or discharging each data line X m before the end of programming to shorten the time required for programming. In other words, the pre-charging circuit 6 0 0 is to accelerate the charging or The charge / discharge acceleration part of the discharge acts. In addition, the precharge circuit 600 can also be considered as an acceleration means to accelerate the change of the current with the change of the data signal, or it can be used to update the charge amount of the data line X m to The predetermined update means works. Fig. 19 is a display diagram for explaining the operation of T pr during the programming of the fourth embodiment. In this example, before the programming of the period t 1 3 to t 1 5 is executed, the precharge control signal Pr e has a high level during the period t 1 1 to t 12, and the precharging circuit 6 0 0 is charged or Discharge. By such pre-charging, the charge amount Q d of the data line X m can reach a predetermined value corresponding to the pre-charging voltage V p (FIG. 18). In other words, the data line X m can reach a voltage slightly equal to the precharge voltage Vp. Then, during the programming period from t13 to t 1 5, at the time t 1 4 during the programming period T pr, the charge amount Q d of the data line X η reaches the charge corresponding to the desired programming current 値 I m量 Q dm. Figure 19 (d) shows a change in the charge amount when a pre-charged or additional current is not used. At this time, at the end of the programming period T pr, the charge amount 尙 of the data line does not reach the charge amount Q d m corresponding to the desired programming current 値 I m. Therefore, there is a possibility that the correct programming current I m cannot be supplied to the pixel circuit 210 to be programmed in the correct tone. If so, in this practical example, by pre-charging to speed up the charging of the data cable, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the precautions on the back before filling this page)-order economy Printed by the Consumer Cooperatives of the Ministry of Intellectual Property Bureau -29- 1221598 A7 B7 V. Description of the invention (4 (Please read the precautions on the back before filling out this page) Electricity or discharge can set the correct brightness of the pixel circuit 2 1 0 In addition, the programming time can be shortened and the drive control of the organic EL element 220 can be increased in speed. When the data line driver 400 is provided on the ground potential side of the data line X m, as shown in FIG. 9 described above. The smaller the programming current I m is, the more the charge amount Q d of the data line is, and its voltage V d is also large. At this time, the pre-charging voltage V p is set to be smaller than the programming current I m (that is, a lower light-emitting hue). ) It is better to have a relatively low voltage. Specifically, the precharge voltage V p is set to a voltage that can precharge the data line to a low-tone range equivalent to the center of the light-emission tone. Voltage VP is set at It is better that the data line is precharged with a voltage equal to the hue near the non-zero lowest luminous hue. Here, the so-called "hue near the non-zero lowest luminous hue", for example, when the entire hue range is 0 to 2 5 5 The meaning of the hue is from 1 to 10. In this way, although the programming current I m is small, the programming can be performed at a very high speed. Whether the pre-charge is printed by the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The judgment is the same as that described in the above embodiments or modified examples using additional current, and can be determined according to the programming current 値 of the previous trip and the programming current 此次 of the current trip. For example, the programming start When the charge amount Q d 0 (FIG. 19) of the m-th data line X m is very close to the charge amount Q dm corresponding to the desired programming current I m, the pre-charging of the data line X m may not be performed. Or, the pre-charging can be judged only when the programming current I m is smaller than the predetermined threshold 此次 this time. When the programming current I m is larger than the predetermined threshold 値, the pre-charging can be judged. This paper is not applicable to China. Standard (CNS) A4 specification (210X297 mm) 30- 1221598 A7 _________B7 V. Invention description ('(Please read the precautions on the back before filling out this page) Pre-charging. Ideally, when the programming current I m is large, The charging or discharging of the data line xm & is performed very quickly, so even without pre-charging, the desired programming current 値 I m can be achieved very quickly. In addition, when determining whether each data line X m is pre-charged Pre-charging can be selectively performed. Moreover, pre-charging is often performed for all the data lines X m, but it has the advantage that the control of the entire display device becomes simple. The color display device is a pixel circuit 2 10 having a three-color component of RGB. In this case, it is preferable to configure the device so that the precharge voltage V p can be set independently for each color. Specifically, three pre-charging power circuits can be set for the information cable for R, the data cable for g, and the data cable for B to set appropriate precharge voltages V p respectively. When three-color pixel circuits are connected to the same data line, it is preferable to use a variable power supply circuit that can change the output voltage as the power circuit for precharging. If the precharge voltage V p can be set individually for each color, the precharge operation can be performed more efficiently. F. Variations related to the pre-charging sequence Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Figure 20 is a display diagram for explaining the variation during the pre-charging period. In this example, the period Tp c (referred to as the “precharge period T p c”) during which the precharge signal Pr is turned on is extended to a period that overlaps with the initial period of the first gate signal ν 1 during the on period. At this time, since the second half of the T pc during the pre-charging period, the two switching transistors 2 1 1 and 2 1 2 required to hold the holding capacitor 2 3 0 (Figure 4) for charging or discharging will be turned on, enabling the The holding capacitor 230 is precharged simultaneously with the data line Xm. Therefore, compared to the electrostatic capacity C d of the data line Xm, the electrostatic capacity of the holding capacitor 230 is suitable for the paper size of China National Standard (CNS) A4 (210X297 mm) -31-1221598 'A7 B7 V. Description of the invention (' When the capacity cannot be ignored, it has the effect of shortening the time required for subsequent programming. 0 (Please read the precautions on the back before filling out this page.) However, as shown in Figure 19, pre-charging is performed before the actual programming begins. It is possible that the influence of the precharge on the storage capacitor 230 can be suppressed to a small extent. In FIG. 20, the programming current Im is maintained at zero (0) until the precharge period Tpc ends. The reason is that when the T pc circulates the programming current I m during the pre-charging period, a part of this current also flows to the pre-charging circuit 600, which consumes ineffective power. However, the increased power consumption by this is If it is negligible, the programmed current I m may flow during the pre-charging period T pc. Fig. 21 is a display diagram for explaining other modified examples during the pre-charging period. In this example, the T pc is in the first pre-charging period. One brake signal V 1 is turned on. At this time, the holding capacitor 2 3 0 and the data line X m can also be precharged at the same time. In this example, the programming current I m is maintained at zero (0 until the end of the precharge period Tp c). Printed from the above description, it can be seen that the pre-charging period can be set before the pixel circuit programming (example in Figure 19), or it can be set to include the pixel circuit programming. The period during the initial part of the program period is also possible (Fig. 20, Fig. 21). Here, the so-called "programming period" means that the gate signal V 1 is on, and the data line X m and the holding capacitor 2 3 0 are connected. The switching transistor (for example, 2 1 1, 2 1 2 in Figure 4) is in the on state. In other words, it is better to perform pre-charging during a specific pre-charging period before the end of the programming period.
